- ItemBiopsy type does not affect the number of stages during Mohs micrographic surgery: a retrospective study(Oxford University Press, 2023) Araneda Ortega, Paulina Belén; Donoso Mena, Francisca; Castro, Juan C.; Uribe González, Pablo Francisco; Rossi, Anthony M.; Hibler, Brian P.; Droppelmann Droppelmann, Katherine Ann; Cárdenas De La Torre, Consuelo Paz; Navarrete-Dechent, CristianMohs micrographic surgery (MMS) is the treatment of choice for high-risk basal cell carcinoma (BCC). However, there are no evidence-based recommendations regarding which biopsy type is more appropriate to obtain tumour samples prior to MMS. Shave or punch biopsies are performed depending on the clinical characteristics of the tumour, surgeon experience and local protocols. However, biopsy type might result in difficult histopathological interpretation and influence the practical implementation of MMS. We performed a retrospective study on 208 consecutive BCCs treated with MMS. Of the 208 BCC biopsies, 42 (20.2%) were obtained by the shave method and 166 (79.8%) via punch. Those obtained with the shave technique had a mean of 1.64 stages vs. 1.69 stages with the punch technique (P = 0.130). These findings suggest biopsy type does not affect Mohs surgery performance. The biopsy type of choice is the one deemed adequate for each specific case to obtain a diagnosis and tumour subtyping., In this study including 208 primary basal cell carcinomas undergoing Mohs micrographic surgery (MMS), there were no differences in the mean number of stages, regardless of which biopsy type was performed (shave vs. punch). The biopsy technique might affect correct subtype identification; however, there were also no differences in the rate of upstaging. Any tissue reaction could also result in difficult histopathological interpretation on frozen sections; however, this was not evident in our study. It seems that biopsy type, shave vs. punch, does not affect MMS performance; thus the more appropriate biopsy type is the one deemed adequate for each specific case in order to obtain a diagnosis as well as tumour subtyping.
- ItemCaracterización clínica y epidemiológica de 200 pacientes con loxoscelismo cutáneo y cutáneo visceral(2021) Droppelmann Droppelmann, Katherine Ann; Majluf Cáceres, Paula; Sabatini Ugarte, Natalia; Valle, Elizabeth; Herrera, Hernán; Acuña Ramírez, DavidBackground:Loxoscelism is an important public health problem in Chile and South America, due to the higher rate of cutaneous-visceral involvement. The diagnosis of loxoscelism is mostly clinical without established diagnostic criteria. There is little evidence to support any treatment used in this condition.Aim:To characterize the clinical features and epidemiology of loxoscelism among patients consulting at the Emergency and Dermatology Services of a clinical hospital between 2013 and 2017.Material and Methods:Review of medical records of patients registered in the electronic clinical record system with a confirmed diagnosis of loxoscelism. Epidemiological, clinical, laboratory tests and treatment variables were analyzed.Results:We reviewed data from 200 patients. Ninety-four percent presented cutaneous loxoscelism and 5.5% cutaneous-visceral loxoscelism. Systemic symptoms were present in 73% of patients with cutaneous-visceral loxoscelism. Patients who developed systemic symptoms had an 18 times higher risk of developing cutaneous-visceral loxoscelism. Laboratory abnormalities were more common in patients with cutaneous-visceral loxoscelism. Not all patients with hematuria had cutaneous-visceral loxoscelism. Most patients required analgesia. Anti-loxosceles serum was not used in any patient.Conclusions:Many questions remain to be answered regarding the diagnosis and treatment of the disease. Studies are required to validate diagnostic criteria for loxoscelism, predictors for visceral involvement and response to treatment.
